sync master is a display and not a system.what system.?rule 1, if system came with XP, then get the restore disksfrom THEM.if not?

is this and XP question ,did you know XP is DEAD !, MS is taking it off line for ever soon.no support, soon. leaving virsus and malware , attacks wide open.so, why use XP?and nobody (legal) sells it, now. (all MS and ask....)you might luck out and find an unused original disk. (NOS)new (old stock)! its called , might be worth big cash as a collectible.?

with the MS logo and all, ive not seen one in may years.i see only 2 on fleabay , and both are from EU, and are illegal.ebay blocks most of these but some leak in. daily. do not buy em.

EX is vastly unsecure. and soon, this willl get far worseif connected to internet and for sure EMAIL.do not run XP if you do things , important to you .better ?if no cash, get a $25 PC with at least 2 core processor.I see them at The GOOD will all the time. with 4gb ram, up date it.and buy W8 upgrade. ask for my free list of how to do that.

I tested W8 on an old pc with a old AMD Simeron, it ran ok.with very little mem. say 2gb.w8 is more efficient, even with metro not working.

or ask friends for a disc to barrow and run repair modedont expect a DELL Xp disk to worn on a non exacty matching DELL system, and the like.

The monitor resolves images across a fixed range of resolutions and resfresh rates.

It is the resolution of the graphics card or graphics adapter that can be changed, not that of the monitor.

Right click on empty space on your desktop > properties > settings.

Left click and hold on the slider and slide to the right in stages.

Each resolution change offers you a test page to accept or reject.

When satisfied Apply > Yes > Ok.

To reset the Refresh Rate:

Properties > settings > Advanced > Refresh Rate.

Then restart your computer.

Be careful not to exceed the resolution/refresh rate range of your monitor (1280 x 1024) / 75.0 Hz because if you do, when you restart the computer, the monitor will be unable to resolve the image and you will get a blank screen and/or an Out Of Range error message.

An out of range problem might only be resolved by using a different monitor to reset the resolution back to within the range of the preferred monitor.

OK, you need to boot up in safe Mode, then change your screen resolution, to say 800x600, or 1024x768, this will then allow your monitor to operate, IF this doesn't work, then you will have to swap out, the Monitor and VGA card to find out which one is faulty.

Check your connections and make sure they are tight, and there are no bent pins. If everything seems ok, you might want to try plugging this monitor into a different computer or plug a different
monitor into yours to determine whether it's the monitor, the video card, or maybe the driver (doubtful on this as you state it seems to be bad somethimes on boot).

The screen probably does work in DOS but the laptop doesn't bother sending it any signal in DOS, it's only when windows starts that windows takes control of the displays and shoots out a signal to the external monitor

I don't know how you would get round this because you can't see your BIOS which you need to go in to and set the primary monitor to external.
